Filed: 1978-08-30
Abstract: PURPOSE: To make the manufacture of sensors easy by arraying two sets of rectangular photoelectric transducers of an equal area in specified combination with respect to the register mark detection of original plate films in photomechanical process work.  
     CONSTITUTION: The 1st, 2nd photoelectric transducers 7, 8 of an equal area are arrayed in such a combination that the long side 10 of the element 8 opposes to the short side 9 of the element 7 and that the short side 12 of the element 8 aligns to the long side 11 of the element 7. The projected light of the register marks 13 forming reticules provided to film original plates, etc. is received in the elements 7, 8 respectively. The film original plate is positioned in one direction by the coincidence of the detection signals by the light received in the elements 7, 8. Positioning of the film original plate in the direction rectangular to this direction is accomplished by the similar photoelectric transducers 14, 15 and the sensor is formed by the photoelectric transducers by two sets of the photoelectric transducers of respectively equal output characteristics. Hence, there is no need for combining a multiplicity of photoelectric transducers of equal output characteristics and the manufacture of the sensor becomes easy.

Inventor: NISHIYAMA SHIYOUICHI
IPC: B60G11/52
Filed: 1980-08-05
Abstract: PURPOSE:To prevent surging vibration and its knocking noise and reduce the number of parts by using a covered coil spring. CONSTITUTION:A covered coil spring 7 is attached to the upper portion of a shock absorber 1 to cover its rod 1a. This covered coil spring 7 comprises a coil spring 8 having the diameter of the strand converged sequentially toward the ends and a tubular soft urethane foamed body 9, the former being bedded in the latter.

Title: Television camera provided with liquid crystal automatic dimmer
Inventor: KARAKI EIJI
IPC: H04N5/238
Filed: 1984-05-28
Abstract: PURPOSE:To obtain automatically proper contrast over a large extent by driving a liquid crystal dimmer panel by a spring driving circuit that inputs a signal of a comparator that detects the size of a video signal and amplifying the signal from an image pickup element corresponding to the signal of the comparator. CONSTITUTION:When the subject is bright, video signals are large, and accordingly, output voltage of a comparator 6 is high. As driving voltage outputted from a panel driving circuit 7 is also high, light transmittivity of a liquid crystal dimmer panel 2 is lowered, and the quantity of light that arrives at an image pickup element 3 is restricted, and adjustment is made automatically to the size of video signals that feeds a picture having adjusted contrast. When the subject becomes darker gradually, video signals become smaller, and consequently, transmittivity of light of the liquid crystal dimmer panel 2 as a loop becomes higher, and the video signals become larger and a picture of balanced contrast is obtained. When the subject becomes further darker, and light transmittivity of the panel 2 stops rising, the output voltage of the comparator 6 drops and the value of gain control of a gain controlling circuit 8 increases. Accordingly, video signals become larger, and a picture of balanced contrast can be obtained.
